68 C Body Disc Brake Conversion

I know it's not an A but I'm sure someone here knows the answer to this question. I have a 68 Monaco and want to convert the front drums to disc. I have searched the c body forum and haven't come up with a good answer. My question is, I have a complete 73 a body front disc setup at my disposal and wonder if these spindles will swap over to my c body? Does anyone know? Any input is appreciated.
